This invention relates to improvements in guides used during the rollingof paper.

When winding paper upon a revolving shaft there is generally a tendencyof the paper to wind in an uneven manner, which action will produce aroll having one end concaved and the other end convexed, in other words,the ends will be inwardly and outwardly coned, instead of being fiat,the result of which causes the machine in which the roll is to be used,to become inaccurate and at times even unmanageable.

The primary object of this invention is to produce a roll whose ends areeven from the core to the outer circumference of the roll. I 7

Another object is to provide such a machine that is of simpleconstruction and very easy of operation.

Another object is to provide a machine of this type that is accurate anddefinite in its operation.

And another object is to provide a machine of this character that iseconomical in maintenance and of comparatively small cost inconstruction.

And a further and also an important object is the provision of such amachine that offers a maximum of safety to the operator.

The manner in which the above and other objects is eii'ectuated willbecome apparent from a reading of the specification taken in connectionwith the accompanying drawings, in which- Figure 1 is a front elevationof the machine.

Figure 2 is a view, partly in section, taken on the line 22 of Figure 1.

Figure 3 is a bottom plan view of the lateral adjusting rack, taken onthe line 3-3 of Figure 1.

Figure 4 is a top plan view, partly in section, of the left hand portionof the machine, and

Figure 5 is a detail View of the retaining means taken on the line 5--5of Figure 1.

Similar numerals refer to throughout the several views.

A roller drum 1 2 which is mounted on a revolvable shaft I3 is laterallystationary but, due to the adjustability of the paper roll core is willcause the roll of paper l5 to be constantly'kept J in contact therewith.

As the right and left hand elements of the machine are identical inconstruction, it is believed that a description of one will suffice fora clear understanding of this part.

A hub l6 has an outer flange I! and, inwardly thereof a bearing surfacel8 with an inner flange I 9 adjacent a paper retainer 20.

Around the bearing portion [8 of the hub i6 is arranged the lower end 2|of a shaft 22 and the similar parts 2 Claims. (c1. 242 65)' shaft 22extends through the block 23, which is attached to a laterally movablecollar 24.

The upper and lower racks 28 and 29, respec tively, Figure 3, with thecog wheel 30, form a lateral adjustment for the blocks 23, as one end ofeach is connected to these blocks.

The collars 24 are slidably mounted on a shaft 3| and as the collar 24is offset, vertically from the block 23, see Figure 2, there will be nointerference with the shaft 22.

. The pins 32 prevent the shafts 22 from going all the way through thecollar 24.

1 Intermediate the shafts 22 is an adjusting means comprising a shaft 33with a handle 34 arranged at its outer end and the inner end of whichhas mounted thereon the rack gear 30.

The shaft 33 extends through a block 35, see Figure 5, and has thereon,and positioned against said block, a ratchet 36, keyed by the key 31thereto, and a cooperating pawl 38, pivoted at 33, the latter of whichis spring-pressed for engagement with the teeth of the ratchet 36 by thespring 40.

With respect to the operation of the apparatus, when the paper startswinding on the shaft 14, the paper is wound loosely, then as thefriction is applied, it starts to become firmer. When this firmnessstarts to take place, the center that was wound loosely on the shaft isforced out of line and the roll starts coning and unless this isstopped, the roll is lost.

In carrying out the present invention, the flanges 20 are drawn to eachend of the roll of the paper as soon as there is enough clearance overthe drum [2 to admit them. Up until that time, there is not enoughfriction on the paper to cause a coning. Flanges 2i! hold in place theloosely wound center of the roll until the roll becomes firm. After theroll becomes firm, there is no more danger of the paper coning,therefore the flanges'do not need to be in the same diameter as the rollof paper. The roll can be made any size, it being only the loosely woundcenter that causes the coning and if the flanges 20 are applied to stopthat, the roll can be made as large as required without any trouble.Some rolls are made as large as fifty inches in diameter.

While I have illustrated and described the preferred embodiment of myinvention, it should be understood that various changes may be madewhile keeping within the scope of the appended claims.

What I claim is:

1. A guide mechanism for rolling paper comprising a reel drum, anelongated winding shaft having its axis parallel to the axis of saiddrum, a pair of hubs revolubly mounted on said shaft and between whichpaper is wound upon said winding shaft and said hubs having acircumferential groove in their outer peripheries, a circu lar retainermember loosely mounted on the shaft between each of the hubs and theroll of paper, a horizontal stationary member mounted above the windingshaft, a pair of slide blocks horizontally slidable on; said stationarymember, a laterally offset guide block integrally formed with each ofthe slide blocks and each having a verti; cal opening therethrough, apair of vertical guide rods extending throughthe; guide;b1ocl;s, a.
